Balaton sound is, as the name is telling already, not taking place in Budapest but many people from Budapest and all over the country come and enjoy a long weekend down in Zamárdi on Lake Balaton for the biggest House Music festival in Hungary. The Balaton Sound is a relatively young festival but has build up to a top destination for international, well known DJs such as David Guetta, Sven Väth or Paul Kalkbrenner. The special thing about Balaton Sound is the location which is right at the beach of Lake Balaton where people hang out in the water, have drinks and listen to music all day long. The festival is also well visited by international people such as Dutch, English or Germans. Balaton Sound is a festival from the same organizer as the Sziget Festival so these guys have best contacts to artists and have a lot of experience on how to make a successful festival. Ticket prices are around the same as for Sziget Festival. IF you plan to go there you should already check for accommodation down there since Zamárdi is a fairly small place and hotels or holiday houses are really rare. You can also camp near the festival but there are many people who do not like camping so check to get a hotel as early as possible.
